When I was testing imap_headerinfo() with an e-mail that had multiple recipients (multiple e-mails in to to: and/or cc: field), I noticed that imap_headerinfo() was failing hard for me on PHP 5.2.10-2ubuntu6.4 with Suhosin-Patch 0.9.7 (cli).
Rather than providing me an array with each and every e-mail address listed in the to and/or cc fields, it was only providing me the first listed. This was disappointing.
[to] => Array
(
[0] => stdClass Object
(
[mailbox] => game
[host] => blunts.com
)
)
Luckily, there was a cool workaround to this problem:
imap_rfc822_parse_headers(imap_fetchheader( string ); which subsequentally worked like a nice little pet would:
[to] => Array
(
[0] => stdClass Object
(
[mailbox] => game
[host] => blunts.com
)
[1] => stdClass Object
(
[mailbox] => dutch
[host] => masters.com
)
)
TL;DR:
So in other words, instead of imap_headerinfo() use imap_rfc822_parse_headers(imap_fetchheader()).
Hope this helps anyone else that runs into this issue from now into the future. This post was suggested by people in #PHP on FreeNode IRC.
When i try to access the same mailbox through pop3 and through imap i get different update infomations.
1. Using imap
header->udate is not the same as strtotime($header->date)
<?php
$mBox = imap_open("{host:143/imap/novalidate-cert}INBOX}", $username, $password); // open as imap
$header = imap_header($mBox, 1); // get first mails header
echo $header->udate;
echo strtotime($header->date);
?>
1. Using pop3
header->udate is the same as strtotime($header->date)
<?php
$mBox = imap_open("{host:110/pop3/novalidate-cert}INBOX}", $username, $password); // open as pop3
$header = imap_header($mBox, 1); // get first mails header
echo $header->udate;
echo strtotime($header->date);
?>
I do not know why this is so, but for this reason, i use strtotime($header->date) together with other values to create my own message-UID because this seems to work independent from the protocol.
I'm not entirely sure why this is, but if you loop through all of the messages in a mailbox, calling imap_header() each time, you can significantly increase performance by calling imap_headers() first.
Compare this:
<?php
$imap = imap_open("{my.server.com:143}INBOX", "user", "pass");
$n_msgs = imap_num_msg($imap);
$s = microtime(true);
for ($i=0; $i<$n_msgs; $i++) {
$header = imap_header($imap, $i);
}
$e = microtime(true);
echo ($e - $s);
imap_close($imap);
?>
With this:
<?php
$imap = imap_open("{my.server.com:143}INBOX", "user", "pass");
$n_msgs = imap_num_msg($imap);
/****** adding this line: ******/
imap_headers($imap)
/***************************/
$s = microtime(true);
for ($i=0; $i<$n_msgs; $i++) {
$header = imap_header($imap, $i);
}
$e = microtime(true);
echo ($e - $s);
imap_close($imap);
?>
The performance difference, as I have tested on several boxes, connecting to several different servers, is that the second code snippet ALWAYS takes 1/2 the time, if not less.
Perhaps it is because imap_headers() retrieves all of the messages on one connection, whereas imap_header() has to make a new fetch request for each message?? I'm not sure WHY it is faster if imap_headers() is called first, but I do know that it is, so I thought I'd pass on the knowledge. If anyone knows why this is, please let me know....
I typically use UID's to identify messages, and recently discovered that the headers I had been pulling using this function and a message-number didn't match the UID's. Instead of worrying about it, I just began using imap_fetchheader() and imap_ rfc822_ parse_ headers() on its output. The only significant difference I immediately noticed was that there is no "udate" property, so I assigned one with the result of strtotime() on the 'date' property.

I had to pass the msgid as array($msgid) instead of an integer. the error "Invalid messageID" is generated if i pass an integer.
Simple little code for checking gmail using headerinfo
<?php /* Created on: 11/3/2008 By Ron Hickey 6tx.net/gmail_mod
Gmail mod for admin panels or you can edit it and convert html results to XML for personal RSS reader */
// enter gmail username below e.g.--> $m_username = "yourusername";
$m_username = "";
// enter gmail password below e.g.--> $m_password = "yourpword";
$m_password = "";
// enter the number of unread messages you want to display from mailbox or
//enter 0 to display all unread messages e.g.--> $m_acs = 0;
$m_acs = 15;
// How far back in time do you want to search for unread messages - one month = 0 , two weeks = 1, one week = 2, three days = 3,
// one day = 4, six hours = 5 or one hour = 6 e.g.--> $m_t = 6;
$m_t = 2;

If you want to extract values from to, from, or other header elements, they are an object and you need to loop over them i.e.
$header = imap_header($mbox, $message_id);
$from = $header->from;
foreach ($from as $id => $object) {
$fromname = $object->personal;
$fromaddress = $object->mailbox . "@" . $object->host;
}
Would give you two variables for the friendly from and the smtp from address
Thanks to www.natrak.net for help with this
